Our Renew / Cancel Index predicts the network's decision on renewal or cancellation for scripted broadcast primetime shows by the end of the 2012-13 season in May, 2013. (includes results from December 31, 2012- May 12, 2013):

-The Cancellation Bear went 20-0-1 on his CBS predictions for the 2012-13 season. (vs. 20-2 in the 2011-12 season)

The "tie" was because the bear had The Mentalist predicted as a "toss up" at the time it was renewed.

With that the cancellation bear bids the 2012-13 season adieu and begins his summer hibernation. The bear and his Renew/Cancel Index posts will return in September. Happy Summer!

Better to Follow The Bear, Than Be Chased By Him. This season you can follow the Cancellation Bear on Twitter via @TheCancelBear. The Cancellation Bear will retweet all the Renew/Cancel Index post titles and links as well as engage in a little more back and forth banter than we do on our standard @TVbytheNumbers Twitter feed.

*shows no longer on the air have their Renew/Cancel Index "frozen" at the point they left the schedule.

** The Renew/Cancel Index does not attempt to predict shows ending because the cast or production company chooses to end them. These shows have the ratings for renewal, but rumored cast/production company moves may end the shows.

From now through the end of the broadcast season in May, the Renew/Cancel Index values will only be calculated using new episodes airing during 2013. However, until new episodes of a show air in 2013, I will keep the "old" Fall predictions in the table.

The Renew/Cancel Index is the ratio of a scripted show's new episode adults 18-49 ratings relative to the new episode ratings of the other scripted shows on its own network. It's calculated by dividing a show's new episode Live+Same Day adults 18-49 average rating by the Live+Same Day new episode average of all the new scripted show episodes on the show's own network. The network's average ratings in the calculation are not time weighted (ex. hour long shows are not weighted twice what 30 minute shows are).

(F) -Fridays: Shows airing on Fridays were renewed with significantly lower than average Indexes.

I can’t believe Rules of Engagement is cancelled. Why don’t you just put some more trash like the Kardas clan or some stupid reality show. This is my favorite show. I won’t watch anything you play now!
